    I have an original MacBook Pro 15" (A1150) that randomly shuts down. Seems to be running very hot. I've already had to replace a bulging battery, and TechTool Pro has indicated a temperature-related S.M.A.R.T. failure with the HD.

    If I downgrade the HD from 7200 RPM to 5400 RPM, will that help with the heat issues? Any other heat-related fixes?

    I know the 13" MacBook Pro suffered a random shutdown syndrome, but I didn't know if the 15" was affected too. TIA.

    All Core Duo models were affected by the "Random Shutdown Syndrome".

    The cause is a combination of poor thermal management and a temperature sensor that is taped down to a heat pipe.

    It's been a long while since I fixed mine, but the fix was simply to take a piece of tape off a temperature sensor and instead place it between the sensor and the heat pipe.

    Do you know where I might find some pix showing the affected parts and fix?
